Situation · Water cut

No water from the tap: keep drinking water separate from the rest.

A water cut can be planned, caused by a fault, or happen because the water is no longer safe to drink. The key is to keep bottled water for drinking and cooking, and reuse the rest.

Frequently asked questions

What people ask most

How much water should I keep stored?

A common guide is about 3 litres per person per day for drinking and cooking, for at least 3 days. In the heat, with babies or with people who are ill, more is better.

Can I drink the water from the water heater?

Water from the hot water tank can be used in an emergency if the system is in good condition, but boil it or treat it before drinking. Use it mainly for washing and cooking.

Does boiling water always make it safe?

Boiling kills germs, but not chemicals. If the authorities say the water isn't safe because of chemical contamination, don't drink it even if you boil it.

Which bleach can be used to make water drinkable?

Only bleach whose label says it's suitable for disinfecting drinking water. Follow the quantities on the bottle and leave it to stand for the time stated.

How do I flush the toilet without water?

If the sewers are working, pour a bucket of reused water straight into the bowl. If they aren't working or you're asked not to use them, use an emergency toilet with bags and absorbent material.
